Title: Blow moulding isotactic polyolefines - to form containers which are separated ultrasonically
Inventor: MACDUFF R
IPC: B29C49/04
Filed: 1971-12-29
Abstract: Container are blow moulded from a continuous length of tube formed from a solid crystalline mono-alpha-olefin polymer of =6C, by passing the tube continuously through a heater to bring it to just below its crystalline m.pt., clamping two mould halves over it, orienting it by moving the mould away from the heater at a greater speed than that of the tube passing through it, expanding the tube to fill the mould, opening the mould to release the container which is then joined to another container by a narrow neck of material, natural contraction causing enough tension to remove the container from the mould, passing the string of containers along a conveyor and separating them by ultrasonic cutting. A prefd. material for the containers, pref. bottles, is polypropylene.

Abstract: A USEFUL N-SUBSTITUTED PYRIDONE            AND GENERAL METHOD FOR PREPARING PYRIDONES                            ABSTRACT     Novel analgesic compositions containing as the active ingredient the compound, 5-methyl-1-phenyl-2-(1-H) pyridone are described,  In addition, a general method for the synthesis of aromatic group N-substituted 2(1-H) pyridones is described wherein a 2-(1-H) pyridone, which may be substituted, is reacted with an appropriate halo-aromatic compound in the presence of an alkali metal carbonate and copper powder. The appropriate aromatic N-substituted pyridone is obtained in excellent yield.          The aryl N-substituted-2(1-H) pyridones have been found to posess uricosuric activity with the 5-methyl-1-phenyl-2-(1-H) pyridones causing significant lowering of serum uric acid levels.  The latter compound caused no irritation on oral administration or when applied to specific target tissues showed no siginificant irritation or other sequelae.

Abstract: TILT AND SWING LOCK MECHANISM      FOR ELECTRIC FURNACE     ABSTRACT OF THE DISCLOSURE         A mechanical tamper-resistant interconnecting lock-ing apparatus is connected to a top charge tiltable direct arc electric furnace which includes a refractory lined fur-nace shell and a removable roof covering a top opening in the shell.         The mechanical locking apparatus of the invention prevents tilting of the furnace during potentially unsafe conditions, i.e., when the removable roof is positioned other than over the shell top opening.  The locking apparatus may not, without considerable difficulty, be dismantled, collapsed, or bypassed to allow possible unsafe operation of the furnace.         The apparatus includes a first locking mechanism which, when engaged, prevents the tilting of the furnace, and a second locking mechanism which, when engaged, prevents the swinging of the roof from over the shell top opening.          A mechanical linkage interconnects the two mechanisms and prevents simultaneous disengagement of both of them.  Also; once one of the mechanisms is disengaged and adjacent por-tions of the furnace are moved relative to each other, the entire locking apparatus is prevented from further movement until the adjacent portions are returned to the position pro-viding lock mechanism engageability.
